A web browser uses the HTTP protocol to connect to a Web server. Calculate the total time required for one request-response cycle, which consists of a 64 byte request packet and a 400 byte packet response. (Assume these are total packet sizes, including headers, etc, and that the processing time at the server is negligible). The link operates at 100 Mb/s and the link distance is 600 Km. [Signal propagation speed is 5 micro seconds per Km of cable.]

i. Calculate how long would it take for one request-response cycle.

ii. Calculate the effect on the delay of increasing the transmission speed to 1000Mb/s. Discuss the implications of this for the network.
